2007-07-17SPI: add 3wire mode flagDavid Brownell
Add a new spi->mode bit: SPI_3WIRE, for chips where the SI and SO signals are shared (and which are thus only half duplex). Update the LM70 driver to require support for that hardware mode from the controller.

2006-06-22[PATCH] lm70: New hardware monitoring driverKaiwan N Billimoria
This driver implements support for the National Semiconductor LM70 temperature sensor. The LM70 temperature sensor chip supports a single temperature sensor. It communicates with a host processor (or microcontroller) via an SPI/Microwire Bus interface. Communication with the LM70 is simple: when the temperature is to be sensed, the driver accesses the LM70 using SPI communication: 16 SCLK cycles comprise the MOSI/MISO loop. At the end of the transfer, the 11-bit 2's complement digital temperature (sent via the SIO line), is available in the driver for interpretation. This driver makes use of the kernel's in-core SPI support.
